lle it known that l, Hanni" Si. Dionmson, a citizen o'i the UnitedStates, residing at llloline, county ot Hoek Isla-nd, and State ofillinois, heve invented certain new and useful Improvements in TractorConncc tions for llari'esting-lllachincs, oi which the following is aspecification.

This invention relates to certain connections adapted to he .interposedbetween a tractor and a lnirvesting' machine for the purpose otcoordinating the power unit and the trailing unit ,into a prncticellyunitary implement without in any way impairing or The invention,-iuithermore, relates to the destroying the capacity et cach of theiinpleineens which are provided for maintaining ments to subservc itsintended functions. the control oi the power unit from the The powerunitwhich is employed in this dri vers seat on the herycster, so thlat itwill invention, is of a, type which derives the be possible tor asinggle operator to control support 'for its rear end, from the groundboth implementa and the invention, urthen wheels oit the trailing`implement, as dis more, relates to the means provic d for tinguishedfrom tractors ot the self-conaffording' the rigidity of connectionrequired tainedl type which are fully capable of being" to coordinatethe implements into a unitary supported and steered independently oit'the structure and at the saine time provide sniiitrailer. cientflexibility to permit the implements to The tractor of theself-contained type, yindiyidnally conform to ground conditions,however, is ordinarily ine ely hitched or which is essential in order toavoid a rack ing or wrenching,r ot the connections, as well as for otherobvious reasons.

The invention, furthermore, is designed to atord o very close connectionbetween the power unit and the binder which facilitates niaiurnveringand rendrs the structure more compact and serviceable.

t is a deteil cit the spring' connection at the saine time are arrangedso as 'to perinit the traine ot the harvester to be tilted forwardly orrearwardly to provide for the vertical adjustment necessary toacconnnodate the falling` `rain without imparting these Variations tothe power nnit, which at all times is designed to maintain its horizontal position. This is important in View ot the tact that anysubstantial Variation from :1. horizontal level will tend to disturb theoil and water levels in the engr-ine and thereby interfere with itseilicient opcration.

it becomes difficult, and in sonno cases ini possible, :tosatisfactorily nninipi'llate the implements in the iield. This isparticularly the case 'where it becomes necessary to reverse theimplements or to turn them about on a short radius, in which cases thedeiicien* cies oi an ordinary connection becon'le the more pronounced, i

lt is perticifilarly desirable `in the case of a self-binding harvesterto provide adequnte connections for uniting the power unit and thetrailing` implement into a substantially integral structure, in View oi'the petit liar diliculties exi'ierienced in the operation ot' harvestingmachines by reason oiE the en cessiye draft to which the gn in side otthe machine is subjected by the contact of the cutter bar with thestanding'- grain.

.ln a machine ot' this type, the center oil draft is necessarilynon-coincident with the center of resistance in View of the necessityfor applying the draft, whether horses or a tractor, at a pointsn'lliciently rcinoi'ed toard the stubble side of the hornefeiter tobetween the powernnit and the stub 'tongue avoid the possibility ciiran'iiviling or crush ci o hervester; f ing down the standing;r grain.The connec ll gg 5 is a derni tions et the present invention are`designed tween the ro to nlnet 4these recognized requirements and nisFig'. 6 a detail showing the hanger connection for the stub tongue.

The connections constituting the present invention are employed inconjunction with the power unit 10, having ground wheels 11, which powerunit carriesl companion rearwardly extending beams 1Q, the forward endsof which are bolted or otherwise secured to a vertically standing` yoke13, the upper and lower arms of which are connected by means of verticalpivots 14 to the power unit in such a manner as to permit ot' alongitudinal swinging movement, but to prevent relative verticalmovement.

The beams 12 serve in part as a mounting for a steering rod 15 which iswithin easy reach from the seat of the driver, located to the rear ofthe harvester', as vi ll be pres ently explained.

The steering rod 15 operates through a suitable gearing 16 which impartsrotation to a shaft 17 carrying a pinion 18, which latter pinion mesheswith a rack 19, the curvature of which is concentric with the axis ofmovement of the beams l2, so that by rotating the steering wheel, thebeams may be swung to right or left to efect the steering' of thecombined implement.

4 The beams 12 are provided with forward and rear hangers 20 and 21,respectively, the lower ends of which are provided with sleeves E22which are journaled upon longitudinally extending pivots 23 carried bybrackets 24: which lie intermediate a pair of longitudinally extendingbars 25 which constitute a connecting element in the form of anelongated frame which is adapted to tilt or rock upon the horizontalpivot bolts 23, which latter are ot sufficient length to alord a slightendwise sliding movement between the parts, which is necessary toaccommodate the connection to certain adjustments presently to bedescribed.

Depending from the bars of the elongated frame, near the forward endthereof, are a pair of hanger bars 26 which are ollset laterally towardthe stubble side of the machine to a slight degree, and these hangerbars are spaced at their lower ends to receive the forward end of a stubtongue 27,

which is pivoted at this point by a pivot 27, and which is connected atits rear end by meansfof a transverse horizontal pivot 28 to the forwardend of the rectangular f It will he understood that the harvester snownis oi? the ordinary or standard type and that the connections whichronstilule the novel features ol' the present mventiou are, simplyapplied or superadded to a harvester ol the standard type without anymaterial change in `its general structure or mode of operation. For thisreason, it is deemed necessary to ret'cr in detail only to thoseportions of the harvester which are in sonic measure concerned with thedetails ot the present invention, and for this reason no reference willhe made to such features oi the harvester as the gathering' reel,conveyor mechanism, binder mechanism, power connections, etc., althoughreference will be made to the iil'anmwork ot the machine which carriesand supports the coimections constituting` the novel features el? thepres ent .ii'iventioiL l rlfhe rectangular itame 2S surrounds thc. bullwheel and' this traine serves as a mounta ing Jfor an luistandii'lgforward .il .trame 3l and a similar rear liran'ie 32, which carry theconveyor and binding mechanisms not shown. The inner legs of theliorward and rear A frames serve as a support lier an intermediatesupporting rod or bar 33, the rear end 3l ofi which loops down and lindsa point of connection to the rear portion ol the harvester frame Q9.This intermediate bar 33 serves as a support for the seat bar 36 whichcarries the seat 3G which located within eau/"reach of the steeringrwheel 3T. This enables thc driver to steer the power unit from a pointat the rear ol' the harvester, and at the same time to exercise contraiover all the levers and appliances required. in controlling both thepower unit and the grain binding mechanism.

ln order to better' accommodate the :tailing,r grain, it is customary insell-binding harvesters of tle type shown, to tilt the frame o?" thema'chinv'e either 'forwardly or rearwardly upon the alined axis allordedby the bull wheel and the ,drain wheel, which tiltingadjustmentfacilitates they gathering' of the grain upon the elevatorrolls preparatory to delivery to the binding; mechanism. lith this endin view, the harvester is halaneed or poised as nearly as it is possibleupon these center` so that hut slight, power will bc required to electthe desired .adjustment.

In the case of the present invenliom these `forward and backwardtilting' movements ol the harvester trame are el'l'ected h v theoperation of a hand IeverQS which is pivoted to a suitablestandard'opstanding lrom the forward A traine, and the l'orward end ofthe lever 38 is conmaztedjby means of a pair oi1 link bars 39 with thestub tongue QT at a point slightly in :ulvance oi" the pivotal point Q8.A suitable latch and segment mechanism 40 serves to hold the lever inits adjusted position and the rear end ot the lever is located withineasy reach oll the driver`s seat. so that hy moving the lever up ordown, the anlgularlily between the han Venter frame and the stub tonguemay be varied, to the end that the main trame will lbe tilted up or downto the desired degree.

Some of the essential features et the pres cnt invention pertain to theprovision which has been made for permitting` these tilting,r movementsof the. harvester trame without imparting' these movements to therearwardly extending beams 12 and to the power unit. These features ofthe invention. will now be described.

The stub tongue 27, at a` point near its -center, h: s upstandingtherefrom a pair ci' parallel guide bars #il which are-slightly curvedat their upper ends 4t2 and are pro vided with a pair of guide slots 13,the eentcr of curvature of which is concentric 'with the pivot pin 2T,

The guide bars 4:1 are connected near their upper ends by means of aspacer bracket 14, and above the spacer bracket, the guide bars aresecured to the elongated. connecting traine by means of guide pins 45entered through the slots 13, which arrangement affords the guide bars alimited up and down movement to accommodate the adjustments heretoforedescribed.

j Springs 1-6 and t7 are mounted on a hanger rod 48 at points above andbelow a bracket lett) rearwardly extend-ing from the bars 25, as' shownin Fig'. 4. rlhe upper and lower faces of the bracket afford bearing.;vpoints for the respective springs, the tension ot which may be regulatedby means of adjusting nuts 50` and 51, respectively, as best shown inFig. l. The bracket 49 projects rearwardly from the elongated connectingframe atl'orded by the bars 2li, and this arrangement ailiords a'lin'iited up and down cushioned movement of a walking;` beam 52, therear end ot which is pivoted toy an ear 53 on the inner rail of the mainframe 29 of' the harvester, the orw:i"d end of the walking` beam beingprovided with a slot 5-1- which receives a` pin entered through thehangers 26.

The d aft from the power unit is trans mitted to a draft rod 56, therear end of which is secured to the stub tongue and the forw: rd end ofwhich is pivoted by means of a vertical pivot 57 kto a/clevis bar 58'which in turn is pivoted by a horizontal pivot 59 to any pair of aseries of holes 5S near the lower end of a pair of depending` draftvbars(30, the upper ends of which are slightly angled to the rear andconnected to the casting which affords the vertically pivoted yoke 13,the point ot connection for the draft rod being substantially invertical alinement with the pivotal center of movement of the 'yokeandits associated? parts. rllhe draft bars 60 are connected by means ofa forward draft bar 61 with a suitable point lof comiection on the powerunit.A j .i

'llherear end ot' the steeringV rod 15 is sup.n

ported and journaled within a lorp lnaclwt (32y upsianding 'from therear end ot an extension suppmting,l rod 33, the forward end ot' lwhichis pi voted between ears (lil which are secured by means ot clainjss 65to the rearwardly ertci'iding beams 12. The c\ tension supporting rod isslidabl y supported at its rear end by means olI a' standard oil whichis mounted upon the intermediate rod or bar l?) of the harif'csterframe, the extension` supporting rod being entered through a loop orcollar (S7 on the standard, which is braced by means ot brace rods (58doscending, down diagonally to the intermediate traine rod 33, as shownin perspective in Fig'.

rlhe extension suppolting,` rod G3, furthermore, serves as a, Ymeans ofsupport for a series ot controlling' levers (i9 located within easyreach from the drivers seat, which controllingl levers are connected bymeans ot rods which extend forward through a guide loop 71 on theextension supporting rod, their forward ends being connected with a'series of bell crank levers 72, located at or near the axial center ofthe yoke 13 which carries the beanis 12. The bell cranks are in turnconnected with suitable controlling devices-carried by the power unitfor control* ling the clutch, brake and other working` portions of theengine. The specilic construction 'et these connections is not materialto an understanding1 oi the present invention and further description isdeemed unnecessary.

ln operation, it will be seen that the driver from his position on theseat at the rear oi the harvester, will be enabled not only to controlthe adjustment of the harvester, but will also be enabled to control theoperation of the ei gine and to steer the combinedI mechanism, which,for steering` j mrposes, is to `he con liiderc (l as a unitaryiniirilement havinn' tour points ot ground support al'l'orded .in lirontby 'the two tractor wheels 11 and at the rear by the bull wheel andgriiliin wheel ot the harvester, with an articulating joint all'orded bythc vertical pivots of the yoke and by the clovis and connections forthe draft rod 56.

This method oi' connecting the parts togather serves to ,Livc'ni'o theimplement, a' whole, the character of a unitary structure which iscapable otbeing steered either while advancing or reversing, and whichis capable oi' action within a much smaller radius than possible where aharvesteris comieoted and trailed behind a trac-toil ot' theselli-contai ned type. lVhile the machine is advancing, practically allthe draft is imparted through the 'low down draft' rod 56, but in caseswhere it is necessary to reverse the machine, the d1at't,will betransmitted mainly through the hangers 2O and 21 which lconnect therearwardly extending beams 12 with. the elongated tramo-wliichfis'pivotenl to tilt ou a horizontal axis.y but is vincapable otindepemleni' vertical mos'ement.

lll/'here it is desired to upwardly tilt the frame, the rear end of thelever 38 Will be depressed and thereafter locked in adjusted positionwhich movement serves to raise the rear end of the stub tongue 2'? whichpivots on the horizontal pivot 27a. movement eauses uptilting oif the'forward end of the harvester Yframe. the joint air'lorded by the rearhorizontal pivot 28 being broken in an upward direction.

During; this movement the harvester traine will tilt upon the axisafforded by the bull wheel and the grain wheel and the lmtiltinp; of theforward end of 'the tramo will, of course, occasion a commensuratedoivntilting of the rear end ol the iE ame, which will result in aslight loweringa el the walking beam 52, the rear end oi which, it willbe noted, is pivoted to tho harvester frame at a point behind its axisof tilting` movement. This slight lowering of the rear end of theWalking' beam 'will result in a. proportionately decreased lolveringofthe rod e8., which5 with its spring; eonneotions unit s the Walking beamwith the rear end of tue horizontally pivoted elongated supportingframe.

lt will thus be seen that as the tornar"V ond of the harvester frame israised or lowered in the adjustment of the eutter bar, the .valkingqbeam `will be corresiwndinirly lowered or raised to a connnensuratedegreen but the movements thus imparted through the spi-ingr connectionsto the horizontal beams carried b v the power unit are so slight as topractically be negligible, With the result that the power unit will hemaintained at substantiallj,T its correct horizontal level yat alltimesi thereby obviatino; the objections ,Which would attend un. un anddown tilting' Aol Jthe rear end of the power unit.

As the rear end oi vthe stub tongue raised or lowered. in the adjustmentefl' the harvester frame, the guide bars l will be correspondinglyraised or lowered, but these movements are accommodated by means of theslotted connection between the' guide bars and the elongated connectingframe, so that the guide bars Will serve their :tunetion of aiordinp; arear connection with the elongated connectingframe without in an)v Wayinterfering with the necessary vertical adjustments of the stub tongue.

In like manner, the slotted connection at the forward end of thewalking` beam a ilords the necessary freedom oi movement tor penmittiugrthese elements to contorni to the iequired adj u stments.

llllien the implement is traveling over rough ground. it is desirable toprovide suflieient flexibility in the eonuec'l'ions lo permit the 'lrontand rear portions ot 'the combined implement to independenily adaptthemselves to ground conditions7 out this flexibility imailforded bymeans oit ."u shrine connection between the Wall-:ing be; n theelongated supporting trame. Thus, the harvester eneounl'ers auelevation. in the ground, the entire rear mechanism.) includH ingn the.liarws :i and the stub tongue.j is permitte.r to roch upwardly on thepivot ill at the lfomvard end ol the stub tongue. which nieven'ient willtend 'to elet-.Yate he end of the *walking beain and tl eby serve toeonipress if' e lower sprin on the vertic l connecting rod i8, n'hieshrine thus serves as a. butler to absorb the sheeh occasioned by therise oit the trailingh haw/ester Without transmitting;1 this upwardmovement in any appreciafible degree to the rear end oli' the elongatediframe and the parts supported from the 'newer unit.

The. slot connection for the forward end of the Walking beam serves toYfreely aceominodate inoveu'ients oil 'this bind, Whether in an upwardor downward direction. thereby relievingl the implement from excessiveshock or strain.. which *would be oecasioncd if the parts n'ei'e rigidly, rather than i ,Xibljv eonnected. Under normal conditions,however, the springs will be maintained in a substantial state oitequilibrium and afford the necessary support to maintain the parts intheir intended position of adjustment. and il? the parts are oitsuiiieient strength the springs m ay be omitted.

ll' will thus be seen that the walleing; beam serves to fiexibly supportthe 'for'lvanlA end of the harvester against vertieal displacement, andthat its eonstriwtiou and mode oi connection with the. harvester trameis sueh that it will accommodate itscliE to the vnecessar)7 tiltingvadjustments of the harvester' but it serv to distribute vertical thruststhe mounting points and: lill..
